Description
- The present invention refers to a device for preparing sheet specimens to perform laboratory test for mechanical characterizations.
- For several applications, it is necessary to obtain the mechanical properties of sheet materials before its use. The performed tests allow selecting materials for given applications, check the properties for current industrial use or determine properties for material improvements, among others.
- In practice, some of these tests require the introduction of cracks in the specimens to measure the material resistance to crack propagation under different loads and environments.
- With the devices currently known for preparing sheet specimens, cracks are usually introduced by applying cyclic loads. These pre-cracking fatigue tests are costly and time consuming.
- This kind of known devices for preparing sheet specimens has the drawback that the preparation is expensive because of its duration and use of costly laboratory equipment.
